A nurse is completing a medication reconciliation for a client prior to his transfer to a long-term care facility. Which of the following actions should the nurse take?

The correct answer is D: Remove duplicate medications of different dosages from the reconciliation list. This is important to prevent medication errors and ensure the client receives the correct dosage. Omitting over-the-counter medications (choice A) can be dangerous as they can interact with prescription medications. Including medications no longer needed (choice B) would lead to unnecessary medications being continued. Comparing current medications to future prescriptions (choice C) is not relevant for ensuring accurate reconciliation.
